What is a figure that has only one curved surface?
A semicircle
How many equal length sides does a semicircle have?
None A semicircle is the shape of a protractor (or half a pizza). It has one straight side and one longer curved edge.
How do you find the perimeter of a shape that has a semicircle?
To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.
Does a semicircle have a curved edge?
Yes.
Is the optical axis parallel to the curved surface?
No. It's straight through the center of the sphere that the curved surface is part of.

Does a semicircle have a curved edge?
Yes.
What shape has a combination of curved and straight lines?
There are infinitely many possible answers. Two of the more common shapes are semicircle and quadrant.
Is the optical axis parallel to the curved surface?
No. It's straight through the center of the sphere that the curved surface is part of.
Is a curved surface or a straight surface better for reflection?
Neither, it depends on what you are trying to accomplish.
Would a shadow cast on Earth be straight or curved?
Well, if you had a shadow cast on earth, it would appear curved because the of the Earth's surface is curved
What is the different between a semicircle and a hemisphere?
A semicircle is a two-dimensional shape that is half of a circle, with a flat edge as the diameter. A hemisphere, on the other hand, is a three-dimensional shape that is half of a sphere, with a curved surface. Essentially, a semicircle lies in a plane, while a hemisphere is a solid object.
What is a straight line or plane that touches a curve or curved surface at one point?
A tangent
What 3d shape is this- 1 curved edge plus 1 flat surface plus 1 curved surface?
its a lens...1 curved edge = a circle, 1 flat surface = back, 1 curved surface = front. (these are used in some battery-less flashlights, as an example.)
How to find the length of the curved part of the semicircle?
A circle is two semicircles put together. The circumference of a circle is the length around it, so half of that would be what you are aiming for. Let's call the circumference "c" and the radius (the straight part of the semicircle) "r". Pi is also needed in this problem, so we can use "π". The equation for the circumference of a circle is c=2πr. Replace "r" with the length of the straight part of the circle, and do the math. Divide your answer by 2.Example:r=2c=2πrc=2π2c=4πc=(approximately)12.5712.57 divided by 2 equals approximately 6.29.The length of the curved part of the semicircle is 6.29!Hope this helps!
